COMPOSITION OF MATTER.

N0 Drawing.

To all whom it may concern:

Be it known that I, LEON INGHASSIA, a citizen of the United States, and resident of Brooklyn, New York city, in the county of Kings and State of NewfYork, have invented certain new and useful Improvements in the Composition of Matter, of which the following is a specification.

The invention relates to a new composition of matter for use on a persons hair in the method. of imparting a permanent wavcto the hair.

It is a usual practice in the art' of permanent hair waving, to divide the head of hair into strands, wrap the strands about metal rods, and after satu'ating the wet strand-with a solution, paste or powder, to apply an electric heater and subject the curled and moistened strand t'o'an intense heat or steam. The substance heretofore applied has been usually borax, to which sodium hyposulphite has been added.

It has been difiicult to impart permanent waves to hair which has been previously bleached or dyed, owing to the fact the dyeing or bleaching operation has taken the life or oil from the hair, whereby when the hair is treated to mould the same, it is broken or otherwise injured by the heating operation. Moreover, in the art of permanent hair waving, it is sometimes quite difficult to wave hair which has not been subjected to a dyeing or bleaching operation, by reason of the'fragile nature of the hair.

Accordingly, the primary object of the invention is to provide a preservative for dyed or fragile hair or the like, which will permit the hair to be permanently waved without deleterious or other injurious results.

My invention also contemplates a hairtreating substance containing such ingredients that it is impossible to injure the hair under the high temperatures usually employed in permanent hair-waving. I obtain this result broadly by combining oil, such, for instance, as mineral oil, with any of the preservatives usually employed in permanent hair-waving. As an example of one such substance, it is noted that a composition composed of sodium thiosulphate, mineral oil and borax, mixed in the following proportion: Borax 80 parts, mineral oil 1 part, sodium thiosulphate 4 parts, has given entire satisfaction.

what is known as white mineral oil, and the sodium thiosulphate is in the powdered form, that is to say, minus its water of crystallization. The aforesaid ingredients are thoroughly mixed, and if desired, water may be added to the mixture to form a paste enabling it to be formed in cakes of convenient size to be positioned in or on the pads usually employed in this process. When in the form of a cake, it is saturated with water before it is wrapped about a tress or strand of hair. It'has been found that the mineral oil and sodium thiosulphate pro-- tects the hair in such a way that it will not become broken or damaged under the influence of the heat or steam which is present in the permanent hair-waving operation, as usually practiced.

Having thus described my invention, what I claim as new and desire to pecure by Let ters Patent is:

1. A composition for use in waving hair comprising a mixture of borax, sodium thiosulphate and mineral oil.

2. A composition for use in hairdressing comprising borax, 80 parts, mineral oil 1 part, and sodium thiosulphate, t parts.

A composition for use in treating hair in the art of permanent hair-waving, comprising a sodium salt and mineral oil of the class of light liquid, oils having a boiling point less than that of paraflin oil.

4. A liquid composition for use in treating hair in the art of permanent hair-waving, comprising an agent including mineral oil for protecting the hair from excessive heating or burning.

5. In the art of "permanent hair waving, the process which consists in molding the hair into a wave formation by heat and while the hair is subject to the protecting action of a composition containing a hair protecting oil.

6. A composition for use in protecting hair from overheating in the art of permaing a relatively small percentage of oil.

7. A composition of matter for use in treating hair in the art of permanent hair waving, comprising a hair protecting salt and a hair protecting oil.

8. A composition of matter for use in treating hair in the art of permanent hair waving, said composition including a hairprotecting oil.

9. In the art of permanent hair waving,

nent hair waving, said composition containthe method which includes the step of protecting the coiled strand of hair with an oil while subjectingthe hair to the heat treat ment incidental to the permanent hair waving' operation.

10. The method of waving hair consisting in giving the hair the desired form, then treating the hair with an alkaline solution and with an oil, and finally heating it.

11. The method of waving hair consisting 10 in giving the hair the desired form, then treating the hair with an aqueous solution of borate of soda and with an oil and finally heating; it.
